How do you find the suface area of a net? Answer: Do the formula for each shape that is in the net.
4(pi)r^2 (4 * pi * r^2)
Surface area = 4*Pi*radius2
To do this question, we have to ask ourself, what formula do you use to find the surface area of a sphere. The answer should be known to you, but it is 4πr2. Since we know how to find the surface area for a full sphere, then finding the surface for a half sphere is just half the job. You use the formula for the full sphere 4πr2, and divide it by 2... so (4πr2) / 2 . Voila!
Assuming the moon to be a sphere, the formula to find its surface area is 4/3*pi*r^3 where r is the radius of the moon.
How do you find the suface area of a net? Answer: Do the formula for each shape that is in the net.
4(pi)r^2 (4 * pi * r^2)
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
Just add the area of the six squares - that gives you 6a2, where a is the length of one side.

Use this formula: 4 x pi x radius2
To find the surface area of a sphere, the formula is: 4pi*r2So plug in numbers: 4pi(4)24pi(16)=64pi
(pi)R2 is the formula for the area of a circle. It won't help you find the volumeof a half sphere, at least not without some calculus.What you need is the formula for the volume of a sphere: V = 4/3 pi R3 .Do I have to explain that the volume of a half sphere is just half of that ?
Use this formula (Ï€ = Pi): Surface area = 4Ï€r2
To find the surface area of a hemisphere, you can use the formula: SA = 2πr^2, where r is the radius of the hemisphere. This formula takes into account the curved surface area of the hemisphere.
